  • Patent number: 4936182
    Abstract: A sharping lever for shortening the length of a vibrating string on a folk harp is described. The sharping lever is mounted along the neck of the harp directly below the tuning pin which secures one end of the vibrating string. The lever includes an L-shaped mounting bracket which is attached securely to the side of the neck of the harp. The sharping lever also includes a rotatably mounted cam which contacts the string along a tip portion. The rotational movement presses the string against a fixedly mounted fret. The fret is located at a position on the mounting bracket so as to precisely define the shortened length of the vibrating string thereby raising its frequency by one-half tone.

  • Patent number: 4932302
    Abstract: A tremolo device for a guitar comprising a flat plate pivotably mounted about a fulcrum on the guitar, a bar secured to the flat plate, at least one tension spring for imparting rotational force to the flat plate and the bar in one rotating direction, against another rotating force derived from a tension of guitar strings, and a tremolo arm manually engageable with the flat plate to oscillate the flat plate and the bar to thereby produce a tremolo effect. The fulcrum is provided by at least two contacts between a pin-shaped member having a substantially half-spherical tip portion on a front end thereof and a concave member having a depression into which the pin-shaped member is inserted.

  • Patent number: 4930389
    Abstract: A stringed musical instrument of the type having a trussrod acting under tension for reinforcing the neck against warping is provided with a system for automatically increasing the tension on the trussrod in proportion to the tension on the strings, thus maintaining both neck straightness and optimal string height with respect to the fretboard and any pickups the instrument may have. The instrument's tailpiece pivots so as to redirect the string tension into tension applied to the trussrod. The tailpiece may be provided with fine tuners or with a tremolo bar. Even on operation of the tremolo bar, there is no tendency for the neck to warp, because the changes in string tension caused by the tremolo bar are automatically and immediately counteracted by the trussrod.

  • Patent number: 4928566
    Abstract: A pair of tension bolts for applying tension to a pair of drum heads are screwed individually into nuts. These nuts are held individually by means of a pair of lug bodies which are fixed to a drum shell. The lug bodies, which are formed by die casting, are connected to each other by means of a connecting member. The connecting member, which has a uniform cross-sectional shape throughout its length, is formed by pressing a metal plate with a predetermined length, or by cutting a metal pipe into a predetermined length. Two opposite end portions of the connecting member are fitted individually in openings at the respective end portions of the lug bodies. A hole is formed in each end portion of the connecting member. The lug bodies and the connecting member are connected so that projections on the lug bodies are fitted individually in the holes of the connecting member.

  • Patent number: 4926735
    Abstract: A musical instrument stand which includes a plurality of mounting stations for holding various musical instruments which is rotatable to facilitate a musician changing instruments quickly and which is heated to maintain the temperature of all instruments at the normal operating temperature to improve and control tonal qualities. The instrument stand includes a base with a platform being generally circular and rotatably movable with rerspect to the base. A heat chamber is defined between the platform and the base to act as a reservoir for heated air. A heating device is adapted to heat air which is transported into the air chamber.

  • Patent number: 4926732
    Abstract: An improved and more versatile, variable capotasto for multistringed instruments, such as guitars, banjos, mandolins and the like. This capotasto is attached to the neck of an instrument by a resilient strap, containing eyelets for adjustment expediently from fret to fret positions. Optionally, a spring loaded or thumb screw adjustable clamp can be made onto the capotasto in order to attach it to an instrument. The unit consists of a Mounting Block which contains 6 (for guitars) spring-tensioned Plungers with padded tips. The Mounting Block also supports a sub-system of 6 vertically installed Cam Levers, each of which respectively can cause any one of the 6 Plunger's tips to press upon an instrument's string behind a fret bar. Hence, this allows the musician to conveniently and quickly change the pitch of any or all strings with this capotasto. The 6 strings can be selectively changed to any combination of open or muted notes, as well as augmenting a multiplicity of open and bar chords.
